FIBER RENOVATYING MACHINE Filed July 11, 1946 I 2 Shets-Sheet 2 Inventor Elmer J Miran.

Patented Dec. 21, 1948 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to improvements in fiber renovating machines.

An object of the invention is to provide an improved fiber renovating machine which will be utilized for flufling old packed fiber or similar material which will be used in various types of p" holstery work.

Another object of the invention is to provide an improved motor driven fiber renovating machine including a rotary combing cylinder and an alternate eccentric drive for the same.

A further object of the invention is to provide an improved fiber renovating machine which will be motor driven and include a combined rotary combing cylinder and a blower for combing and flufiing packed fiber materials for use in renovating upholstery and for renovating mattresses or other articles in which the filling becomes packed.

Another object of the invention is to provide an improved fiber renovating-machine which will be of a portable type operable in any location where there is a source of electric current supply.

Another object of the invention is to provide an improved fiber renovating machine which will be highly efiicient in operation, and relatively inexpensive to manufacture and produce.

Other objects Will appear as the description proceeds.

In the accompanying drawings which form a part of this application,

Figure 1 is a vertical sectional view taken through the improved fiber renovating machine;

Figure 2 is a vertical sectional view taken through the improved fiber renovating machine at right angles to the showing in Figure 1;

Figure 3 is a plan view looking into the open top of the improved fiber renovating machine;

Figure 4 is a front elevation of one of the end bearings for the adjustable feed rollers, and

ure 5 is a sectional view taken on the line 5-5 of Figure 4.

Like characters of reference are used throughout the following specification'and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an improved fiber renovating machine having a substantially rectangularly shaped housin l formed with the bottom, 2 and a cover 3 hinged at 4 to the upper end of said housing or casing l.

Secured to the inner surfaces of the opposite sides 5 and E of the housing I, are the reinforcing strips 1 and 8 between the upper ends of which the bracing rods 9 and I0 are disposed to extend transversely of the housing I.

Suitable bearings H and 12 are secured to the inner surfaces of the strips 1 and a and support the shaft [3 on which the combing cylinder 14 is fixed. A plurality of upwardly extending strips iii are fixed longitudinally to the outer periphery of said cylinder l4, and serve the purpose of a blower when the cylinder is rotated. Angularly disposed rows of outwardly extending pins l5 are also fixed to the outer periphery of the cylinder l4, and engage and tear apart the packed fiber as it is fed to the combing cylinder [4.

An inlet aperture I! is formed through one end of the housing I, and a U-shaped fiber feeding :tray i8 is hinged at H! immediately below said inlet ll so that the tray may be dropped to lie next to the cabinet or housing I when not in use, or it may be pulled upward to extend outwardly at right angles to the cabinet when the machine is being operated.

The vertically disposed end bearings 23 are formed with the vertical bearing grooves 2| and are secured to the reinforcing strips 3 and 8 adjacent to the inlet opening I1, and on a level therewith.

A pair of rubber feed rollers 22 and 23 are provided with the pulleys 24 and 25 formed at their opposite ends and with the centrally disposed shafts 2B and 21 which are loosely and slidably received in the grooves 2| in the end bearings Ell.

The oppositely set eccentrics 41 and 48 are secured to the shaft 13 adjacent the ends of the combing cylinder [4, and support the strap arms 29 and 30 which are held on said eccentrics by means of the bolts 3!. The arms 29 and 33 extend rearwardly toward the rollers 22 and 23 and are formed with the clamping heads 32 and 33 in which the ends of the belts 34 and 35 are secured. The belts 34 and 35 extend rearwardly under the upper roller 22 and about the pulleys 24 and 25 on its ends, to form a figure 8, also being in contact with the pulleys 24 and 25 on the lower roller 23, and from thence downwardly to connect with the coil springs 36, whose opposite ends are secured to the bottom 2 of the cabinet by means of the fastening hooks or eyes 37.

A large pulley 38 will be secured on the shaft 3 to support the driving belt 39 which will extend downwardly over the small pulley 4% on the electric motor 4! secured to the cabinet base 2.

An outlet opening 42 will be formed in the rear of the cabinet or housing I opposite the lower portion of the combing cylinder l4, and an upwardly inclined fiber discharge guide chute or strip 43 will be positioned in the lower end of said outlet opening 42, whereby the combed fiber will be blown through said outlet opening by the fan or blower efiect of the said strip l5 on the combing cylinder it.

The operation of the machine will be as follows: The motor ll is started thereby rotating the combing cylinder It, and as the cylinder rotates, the oppositely set eccentrics All and 43 will alternately move the belt supporting arms 29 and 3B upwardly, which action will pull on the belts 3 4 and 35 to rotate the rollers 22 and 23 to feed the fiber in toward the combing roller l4. As one eccentric arm is operated, the other arm will be released and the springssecured to the floor or bottom 2 of the cabinet I, will pull the belts downwardly to their lowermost position.

From the foregoing description, it will be apparent that there will be an intermittent alternate operation of the eccentric arms which will.

drive the feed rollers very slowly, so that the packed or matted fiber will be held therebetween as the pins of the combing roll loosen up and tear the packed fiber apart to fluff the same, and to which it is blown and discharged through the outlet in the cabinet or housing ready to be used in the reupholstering oi furniture or for the rebuilding or renovating of mattresses, etc.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from thespirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A fiber renovating machine including a cab inet having opposite inlet and discharge apertures, a combined combing and blower cylinder rotatably mounted in said cabinet, means for driving said cylinder, opposed eccentrics on the ends of said cylinder, cooperating feed rollers mounted between said inlet apertures and said cylinder, and belts connected between said eccentrics and said rollers for alternately driving the opposite ends of said rollers.

2. The subject matter as claimed in claim 1, and resilient means connected with said belts for alternately retracting one belt as the opposite belt is being pulled by an eccentric to rotate the rollers.

3. The subject matter as claimed in claim 1, resilient means connected with said belts for alternately retracting one belt as the opposite belt is being pulled by an eccentric to rotate the rollers, and slidable bearing guides for said rollers.

4. The subject matter as claimed in claim 1, resilient means connected with saidbelts for alternately retracting one belt as the opposite belt is being pulled by an eccentric to rotate the rollers, slidable bearing guides for said rollers, and a pivoted fiber feeding tray supported on said cabinet at said inlet aperture.

5. The subject matter as claimed in claim 1, resilient means connected with said belts for alternately retracting one belt as the opposite belt is being pulled by an eccentric to rotate the rollers, slidable bearing guides for said rollers, a pivoted fiber feeding tray supported on said cabmet at saidinlet aperture, and a discharge guide chute in said cabinet adjacent said discharge aperture, 7

6. The subject matter as claimed in claim l, resilient means connected with said belts for alternately retracting one belt as the opposite belt is being pulled by an eccentric to rotate the rollers, slida ble bearing guides for said rollers, a pivoted fiber feeding tray supported on said cabinet? at said inlet aperture, a discharge guide chute in said cabinet adjacent said. discharge aperture, and ahinged cover for said cabinet.
